mod_jem: more options to decide which events are shown (#776)

- additional type "unfinished" which checks enddate/endtime
- added back offset (in hours)
- no enddate uses startdate
- no endtime uses "23:59:59"
mod_jem_wide: add unfinished + offset for events query (#776)
mod_jem_wide: use time matching date chosen (#777)
mod_jem_teaser: add unfinished + offset for events query (#776)
Fix little typo in MOD_JEM_*_OFFSET_HOURS_DESC
Fix #778: list events only once on My Attendings
Fix limitstart when limit changed (frontend views, #786)

views: attendees, categories, category (events), day, editevent (choose venue, contact), eventslist, myattendances, myevents, myvenues, search, venue, venues
Fix limitstart when limit changed (backend, #786)
Fix ordering of categories, hiding root (#788, #558)

- use lft instead of ordering
- remove "root" from most selection lists
  (also on all menu items, so button "No Category" must be used where applicable)
- improved category selection boxes a bit
REF #788: clear jem_categories.ordering, top category not required on Categories view
REF #782, #787, #791: legend on categorycal, view params, archive, ...

- JEM version set to 1.9.8 (xml)
- show (reduced) legend on category calendar with event count
- fix params of category (list) view
- show event count on subcategories (also used for Show empty subcategories)
- regard "task=archive" on subcategory links (Category/ies views)
- harmonize view params to get more consisent look (menu items)
- on Venue calendar move id from params to link (uri) conform to all other views
- add back colorpic on Week calendar
- internal: startdayonly now means "start day only" and not "all days" - reduces developer's confusion
frontend open dates option for eventslist (#792)
all modules: fix filter by category or venue (FIX #774)

...and ensure ids given are positive, non-zero numbers only

Note: This is not recursive. User must specify every (sub)category id he wants to see events from.
